The TCP Rear Pushrod Suspension System enables dramatically improved handling performance for Classic Mustangs and Fords in a high-tech, self-contained package. The original leaf spring suspension relies heavily on the springs to handle rear end housing movement in six-directions as well as torque reactions during acceleration and braking. We’ve replaced the leaf springs with double-adjustable VariShock™ coil-over shocks, tubular trailing arms, watts link assembly, and heavy-duty torque arm. This separation of control jobs to individual components enables a superior level of positioning and geometry accuracy. The result is consistent, predictable handling suitable for the most demanding of performance applications. Additional benefits include significant improvement to chassis rigidity and extremely precise tuning adjustments such as ride height, wheel base, housing alignment, instant center, pinion angle, shock valving, as well as a choice of spring rates. High quality construction combined with a wide range of adjustments make this system equally at home on the street, strip, or road course.
